Title: Improvements in the manufacture of filaments, yarns, bristles, straw, and like materials having a basis of organic derivatives of cellulose
IPC: D01F2/28
Filed: 1935-05-02
Abstract: Artificial filaments, yarns, bristles, straw, and like products having a basis of an organic derivative of cellulose have incorporated therewith a finely divided chlorinated starch, obtained by treating starch with chlorine or cold hydrochloric acid.  The products have reduced lustre and may be further reduced in lustre by treatment with hot aqueous media.  The chlorinated starch may be incorporated in the spinning solution either directly or by first dispersing in a dilute solution of the cellulose derivative.  The spinning solution may also contain pigments, fillers, dyes, lakes, fire retardants, plasticizers, sizes, oils such as olive, teaseed, cotton seed, animal, or mineral oils, sulphonated oils, fatty acids, glycols, or glycerols.  The filaments may be produced by dry or wet methods. They may be used as continuous filaments or short lengths in the production of fabrics.  They may be weaved, knitted, or netted. In an example, chlorinated starch slightly soluble in water is milled with a dilute solution of cellulose acetate until the particles are below 1 micron.  The solution is mixed with a stronger solution of cellulose acetate.  The mixture is filtered and spun into filaments. These are formed into yarn and circular knitted into fabric.  The fabric is treated with hot soap solution.

Title: Improvements in and relating to methods and apparatus for ore separation
IPC: B07C5/344
Filed: 1947-05-15
Abstract: 654,150. Magnetic separators. TRIGGS, W. W. (Bolidens Gruvaktiebolag). May 15, 1947, No. 13133. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 17, 1947.] [Class 72] In a method of and apparatus for separating ore into three portions, the crushed ore is passed through an alternating magnetic field, the variations produced in which are used to actuate mechanical means for separating the ore into a portion of relatively high magnetic susceptibility, a portion of relatively good electrical conductance, and a residue. As shown, Fig. 1, crushed ore in conveyed on a belt 13 into the region of balanced opposed secondary coils 3, 4 in which current is induced by a primary coil 1 connected to an A.C. source 2. The coils 3, 4 are connected through rectifiers 3<SP>1</SP>, 4<SP>1</SP> to systems (only one being shown) of amplifier 5, relay 6, motor 7 and wheel 11 with paddles 10. Upon material of good conductance coming opposite coil 4 the induced voltage in the latter is increased over that in coil 3, the resulting current actuating the motor 7 and wheel 11 to sweep that material into a hopper 15. Magnetic material on the other hand reduces the induced voltage in coil 4, and a second amplifier, relay, motor, paddle wheel system is actuated thereby to sweep such material into a corresponding hopper. The gangue &c. not affecting the secondary coils is carried on to a hopper 16. The rectifiers 3<SP>1</SP>, 4<SP>1</SP> may be across or in series with the coils 3, 4 and may be replaced by Gratz circuits; the coils 1, 3, 4 may be below the belt 13, Figs. 2, 3, (not shown); a pivoted tongue 17, Fig. 4, (not shown), may replace the wheel 10. It is also stated that rectifiers may be dispensed with and the phase displacements in the voltages in coils 3, 4 produced by magnetic or conducting material may be employed to actuate the mechanical separating devices.

Title: Improvements in or relating to sweep generators
IPC: H03B23/00
Filed: 1968-03-19
Abstract: 1,211,905. Frequency modulation; transistor switching circuits. TELONIC INDUSTRIES Inc. 19 March, 1968 [20 March, 1967], No. 13161/68. Headings H3R and H3T. A wide range sweep generator comprises: a number of oscillators 50, 51, 52, each operable over contiguous bandwidths #f 1 , #f 2 , #f 3 ; means 40 for producing sequential sweep signal and sequential switching signals; and a switching circuit 80 responsive to the switching signals for sequentially connecting the oscillators to the output 85. A ramp generator 23 produces two sawtooth signal RAMP I and RAMP II which are fed to unit 40 to produce sequential pulse control signals (90, 91, 92, Fig. 3, not shown) for the switch unit 80 and sequential ramp signals (100, 101, 102, Fig. 4, not shown). During a first time period oscillator 50 is swept over its range #f 1  by the first ramp signal (100) and its output is connected to its line 85. During a second time period oscillator 50 is disconnected from line 85, oscillator 51 is connected to line 85, and the second ramp signal (101) sweeps this oscillator over its range #f 2 . Similarly, during a third period oscillator 52 is swept over its range #f 3 , giving a total sweep range #f = #f 1 + #f 2 +#f 3 . unit 40, Fig. 6.-The RAMP I Control unit 40, Fig. 6.-The RAMP I signal applied at input 30 varies linearly between - 14 volts and - 23 volts. At - 14 volts, transistors 145, 146, 172 are all saturated, and the three outputs 60, 61, 62 are all at - 14 volts. As the input falls towards - 23v transistor 145 comes out of saturation and the potential at terminal 60 starts to fall. The circuit parameters are so chosen that the output at 60 reaches its limit of - 23v when the input at 30 is - 17 volts. At this point transistor 146 comes out of saturation and the potential at output 61 falls until it reaches - 23v when the input is - 20v. Transistor 172 then similarly comes out of saturation to produce the output ramp at 62. These three ramp signals control, for example, varactor diodes in the oscillators. The RAMP II signal is applied to input 31 and varies between + 14 and + 23 volts. Initially, inhibit gate 221 is saturated switching on transistor 223 to provide - 24v at output 70<SP>1</SP>, and outputs 71<SP>1</SP>, 72<SP>1</SP> are at 0v. As the ramp waveform increases, the signal at the collector of transistor 201 increases until at 17v stage 210 switches to saturate transistor 233. Output 71<SP>1</SP> then falls to - 24v and an inhibit signal is fed via diode 240 to turn off transistor 221 and hence transistor 223. Output 70<SP>1</SP> therefore returns to 0v. A further increase in input to 17v causes stage 211 to switch and saturate transistor 263 thus producing a - 24v signal at output 72<SP>1</SP>. This output also holds transistor 221 off and resets switch 210 to return line 71<SP>1</SP> also to 0v. The frequency range of the oscillators is arranged to overlap so that small sweeps in the transitiqn region from one oscillator to the other may be made without the necessity of switching oscillators.

IPC: D05B63/00
Abstract: 133,579. Fairweather, W., (Singer Manufacturing Co.). Jan. 31, 1919. Threads, controlling otherwise than in stitchforming.-The looper thread nipping device is opened on the reversal of the machine by a normally inoperative mechanism. A pawl 51, Fig. 5, is pivoted upon the upper spring 43 of the nipping device and normally rides silently and ineffectually on a cam 47. The lowest point on the cam is such that the point of ccntact of the pawl with it lies on the line joining the centres of the cam and the pawl pivot, and that the pawl just doesnot contact with a stop 54. When the machine is reversed and the lowest point of the cam passes the pawl, the pawl is carried backward into contact with the stop 54 and thereafter, as a strut, rises with the cam and lifts the upper threadnipping spring 43. The needle-threads pass under light springs 57, Fig. 8, carried by the needle, and these prevent the formation of loops of needle thread on the point of the needles during reversal.

Abstract: 160,187. Brown, A. A. May 28, 1919. Folding boxes; fittings, internal.-In a collapsable cardboard box for holding a gas mantle, the mantle is secured in place by a pair of shelves, and the parts are so arranged that the final folding movements performed in setting up the box serve to press one or both shelves firmly down upon one or more of the mantle lugs. In one arrangement, the box and the mantle shelves are made from a single blank shaped as shown in Fig. 1, the blank being cut as indicated by firm lines and creased or scored as indicated by broken lines. In setting-up the box, panels g', g<3> are turned at right-angles to a mantle shelf h, the three parts g', h, g<3> being arranged adjacent to the edges of the panel d<1> as shown in Fig. 2. The parts c<1> - - c<4> are then folded in tube fashion round the parts g<1>, h, g<3>, a flap c' being tucked between the parts c<1>, g<3>. After the mantle has been placed in the box, a second shelf m is turned inwards, leaving wing-pieces n projecting from the box. When the panel d' is folded to close the box, it presses on the wing-pieces n and turns down the shelf m so as to lock the mantle in place. In another arrangement, the main portion of a blank shaped as shown in Fig. 3 is bent into tubular form so that a flap o<5> overlaps a panel o<1>, and a shelf q with a wing portion r is turned inside the tubular part and pressed into position by a flap p, as shown in Fig. 4. A flap s' is then turned inwards against the top of the box, and a second shelf t with a wing portion t' is turned in and pressed into place bv a closing-flap s. A projection t<2> on the shaft t is arranged to engage a side of one of the mantle lugs. The shape of the box blank may be modified; in one modification, a blank shaped somewhat similarly to that shown in Fig. 1, is provided with a securing- tongue, which projects from the panel g<3> and is adapted to engage a slit formed near the opposite corner of the blank. The shelves may be formed from a sheet of material separate from the main blank.
